The great greek chemist; saved1986 has found the answer (just joking, I am a lousy chemist)!

If you like chocolate, you are eating stearic acid!

It occurs in many animal and vegetable fats and oils, but it is more common in animal fat than vegetable fat. The important exceptions are cocoa butter and shea butter whose fatty acids consist of 28�45% stearic acid.[2]

Here is another article that may put your fears to rest!

I used to buy vitamin C capsules until I realized they contained flow agents such as magnesium stearate.

Now I buy ascorbic acid as a powder as well as size "00" vegan capsules, and fill them myself. No fillers, no flow agents, no additives of any kind.

In fact, I try to buy all my supplements as a bulk powder, from a reliable source (nothing from China) and that way I'm not paying extra for fillers.

Anyone can use supplements that contain magnesium stearate, that is their choice. My job is to make people aware of the possible danger, and I did my job!

If people in their 80's, 90's and beyond are eating magnesium stearate they must have a stong and healthy body chemistry but for someone like me who was raised on processed, dead, sugar foods I need to be as perfectly clean as I can so I can live the longest I possibly can. I don't have a strong body chemistry. I didn't grow up eating raw milk, organic vegetables, nutrient dense grains, non-gmo foods, free-range meats, etc.. These older people seem to have stronger body compositions because of the foods that built their body.

This is what I found on the internet today:

Magnesium stearate, stearic acid and calcium stearate, made by hydrogenating cottonseed or palm oil, are used throughout the supplements industry as lubricants. They are added to the raw materials in supplements so that production machinery will run at maximum speeds. These fatty substances coat every particle of the nutrients, so the particles will flow rapidly. This ensures that production schedules will meet profit targets.
Cottonseed oil has the highest content of pesticide residues of all commercial oils; cotton crops are heavily sprayed. In the hydrogenation process, the oil is subjected to high heat and pressure in the presence of a metal catalyst for several hours, creating a hydrogenated saturated fat. Hydrogenated vegetable fats contain altered molecules derived from fatty acids that may be toxic. The metal catalyst used in the hydrogenation process may also contaminate the stearates produced (see Erasmus, Fats and Oils).
While toxicity is one problem, decreased absorption is another. In a study published in the journal Pharmaceutical Technology, the percent dissolution for capsules after 20 minutes in solution went from 90% without stearates to 25% with stearates (article available from us upon request). This delays the absorption of nutrients. Individuals with impaired digestion may have particular difficulty absorbing nutrients coated with stearates. Another problem with stearates: concentrated doses of stearic acid suppress the action of T-cells, a key component of the immune system. The article "Molecular basis for the immunosuppressive action of stearic acid on T cells" appeared in the journal Immumology in 1990.
